Java Linux port for Strong ARM platform

It's finished!
Well, the code anyway. I have now finished the first version of a java class wrapper for the linux joystick driver, written a java gui test program, and it works! ... er, At least it works on my system, with my jdk, on my distribution, with my joystick, so I'd like to make it available for others to test. But, as this is my first linux programming project, I have no clue how to build appropriate makefile for: 1- gotta build the native .c file into a shared library 2- build the java files into a jar 3- need to install the .so created in step 1 into an appropriate directory. (In the LD_LIBRARY_PATH?) 4- put the .jar file in an appropriate directory in the classpath. 5- How do I put an appropriate "license" on it so it can be used freely? I'd like changes to come back to me, so I can be the maintainer of the thing, but want people to use or improve it, and make it useful. So,I think there should be: make clean make configure - do I need this? maybe to find out where the linux jni includes are? make - to build the so, and the jar files make install - to install the stuff appropriately Should I write the doc in javadoc since it's just a set of classes for an api? Or in a readme? Both? Where do I include the license descriptions? Is there a "template" or sample license file somewhere that I can use? I appreciate any help in this, since I've never attempted this stuff, and have never done makefiles, shell scripts, etc. Where do I start?

JDK 1.2 pre-v1: Missing shared library
Hi, thanks for your work on porting JDK 1.2 to Linux. I've downloaded JDK 1.2 pre-v1 for i386 and have tried to run it on a Pentium PC with 2.0.36 kernel (SuSE 6.0 distribution). Everything is running fine as long as no X11 window has to be opened. In that case, a shared library libstdc++-libc6.0-1.so.2 is not found (detailed error message attached).

Re: Clipboard cut & paste and JVM/X/Swing
This was the first thing I looked at in the source, the reference to "CLIPBOARD" is still hard coded in the source which I think is calling native code to set up the selection using XLib, atoms and all that, so I would guess the answer must be no. I think this is a platform specific issue for X. If it uses the other, then I suspect it would interfere with any applications relying on selections for un-do ? >Clipboard interaction between JFC/Swing and other XFree86 apps > >Does the JVm application cut & paste between the CLIPBOARD buffer and/or >the PRIMARY buffer ? > >Pete > > >-- >To UNSUBSCRIBE, email to [EMAIL PROTECTED] >with a subject of "unsubscribe".

Re: terrible fonts in linux-jdk1.2
I get the warning about zapf dingbats too (lots of times on starting a single swing app) and the application seems to get the font metrics wrong - the text appears at the normal size, but there are huge gaps between lines (as if it was all doublespaced).

The same issue affects jEdit 1.4final. I don't have any other swing/AWT applications to test, but I do know that jEdit works okay on JDK1.2 on windows. If there's any other information I can give to help track this down, let me know. By the way, the source code to jEdit is available at the url that I gave, in case that helps tracking down the problem. I doubt it's a jEdit issue, but it might help to figure out which method it's calling that isn't working. Oh, and I forgot to give information about my system before - it's a Red Hat 5.2 box (upgraded from 5.1) with KDE/kwm as the window manager. I haven't changed anything with the X server or the X fonts from the default that came with RH.

bugs bugs bugs, maybe not.
Hello; I tried running jdk1.2 on RedHat 5.2 with no luck. No matter what I do libjava.so is not found. So I upgraded the libs, such as glibc, libc, egcc, libstdc++, etc. I still get the same error, plus, I can not run jdk1.1.7 due to a missing symbol. A suggestion is to provide different compiled versions, such as one for Debian, SuSE, RedHat 5.2 and 5.8.X, etc., for both, jdk1.1.7 and jdk1.2 like KDE does. I volunteer to do the RedHat 5.2 and 5.8.X.

My big stupid mistake
Ok, I'm really stupid. Please don't flame me for how stupid I was. I was writing a Makefile and testing it. In the make file I have: #make a directory we can use for jarring things up mkdir jar #copy the com/kevinsworld/. directory structure cp -r com jar cd jar #don't want java files in the jar, just class files rm com/kevinsworld/linux/devices/*.java #create the jar jar -c0vf com cd .. rm -r jar First problem: the cd apparently doesn't work in the make file, so it actually removed my java source files from where I really, _really_ didn't want them removed. Oh, where is linux's undelete feature! (You know, the "gotta protect the morons" feature...). So, how do I "cd" in a makefile? Jar only works correctly if you're in the directory of what you want to jar. i.e.: if I am in jar and say "jar -c0vf jar/com" it puts the files in the jar as if they were in package jar/com/kevinsworld/... rather than com/kevinsworld/... So, how do I cd in a makefile? Second problem. I was stupid and didn't think to copy my source files elsewhere. This is a relatively small project I was just working on and hadn't backed up yet. (I already admitted to stupidity). Can I disassemble my java .class files to get something to work from to recreate the source?

Make executes each command line in its own subshell. You ran the "cd" command in a shell. Then you ran the "rm" in another shell. And so on. If you want commands that change the shell environment (such as changing current directory) to affect later commands, you need to combine them in the same line, using the ";" separator.
